0f scarifier shown in the drawing '1S 0110 which is applied as anattachment t0 the rear end 01 the tank 1 0f a 10ad 101101 und c0nsists0f a series of t001 holding bars 2 t0 the 10211 end 0f each of which isclamped by caps 2 a 13001 3 of usua1 The forward ends of the t001holders are keyed 130 a draft bar 41 which is 1'0- tatab1y mounted inbearing 5 ds 01 frame members 5 Wh10h are holding bars are als 6 Wh10hextends transversely across the ent1re series 01 bars a a gauge wheel ntreferred Co.

nd has 011 each each of the bars 2 havmg an czxrried by 1 as sh0wn Thet001 0 c0nnected with a shaft end thereof integrally formed upwardlyprojecting sp1it 0011211 8, through which the shaft 6 extends, a b01t 9being employed t0 clamp the 0011211 b0 the shaft in the fashion sh0wn inthe prior patent.

ember 10 is pivoted on and applying pressure t0 the scarifying* t001s.

Regardless of the connections with the draft bar 4 und shaft 6 it hasbeen found that these t001 holding bars have a tendency to springsidewise in meeting obstructions due 130 the fact that in the course 0ftin1e the connections become m010 01 less worn an 1 loose and also tothe inherent yielding of the metal. T0 overcome this difiioulty there isemployed a bar 13 extending transversely across the entire series oft001 holding bars and connected therewith. The preiemble manner 0fconnecting the bar is 0 clamp the sa1ne 130 the rear sides 01 the ears 8by the b0lts 9.

By this construction 110 one 0f the tools und its holder can movesideways without dragging the entire series 0f C0018 and holders with itwhich is impossible under ordinary working conditions.

I-Iaving thus described my invenoion, I claim:

In a device 0f the character described, a serieg 0f pivoted t001 holdingbare, each 0f said bars having an integrally i0rmed split 0011m, and ashafc extending across the entire series 0f bars and through saidcollars, means 101 clamping saicl collars t0 said shaft, und a tie barextending across the kantire series of t001 holding bars and secured 130said collars by said claniping means.

In testimony Whel'e0f, I have hereunto set my band this 17th day ofDecemb0r,

WALTER J. ENDTER.
